AB=BC=d A M source movies with speed `(C)/(2)` and some observe is at C at rest Velocity of sound is C when is A reaches B is if f is actual frequency, frequency of sound detected by 'C'

A source of sound of frequency 1.8kHz moves uniformly along a straight line at a distance 250m from observer. The velocity of source is 0.8C where C is the velocity of sound. Find out the frequency of sound received by observer (in kHz) at the moment when the source gets closest to him.

A source of sound which emitting a sound of frequency 600 Hz is moving towards a wall with a velocity 30 m/s. Three observes A, B, C moving with velocity 20 m/s, A away from the wall and B towards the wall and Inside the source, Velocity of sound in air is 330 m/s. Find the frequency of reflected sound observed by observer B

A source of sound which emitting a sound of frequency 600 Hz is moving towards a wall with a velocity 30 m/s. Three observes A, B, C moving with velocity 20 m/s, A away from the wall and B towards the wall and Inside the source, Velocity of sound in air is 330 m/s. Find the frequency of direct sound observed by observer A

when a source is going away from a stationary observer with the velocity equal to that of sound in air , then the frequency heard by observer is n times the original frequency . The value of n is

A source of sound is travelling towards a stationary observer. The frequency of sound heard by the observer is 25% more that the actual frequency. If the speed of sound is v, that of the source is

When both source and observer approach each other with a speed a equal to the half the speed of sound, then determine the percentage change in frequency of sound as detected by the listener.

A source of sound which emitting a sound of frequency 600 Hz is moving towards a wall with a velocity 30 m/s. Three observes A, B, C moving with velocity 20 m/s, A away from the wall and B towards the wall and Inside the source, Velocity of sound in air is 330 m/s. Frequency of directed sound observer by observer C.

A sound source moving with speed 50 m/s along x-axis and observer at rest on y-axis.If the frequency observed by observer when source crosses the origin is 96 Hz, then the original frequency of source is :(speed of sound is given medium is 200 m/s)

When a source of frequency f_(0) moves away from a stationary observer with a certain velocity, an apparent frequency f' is observed. When it moves with the same speed towards the observer, the observed frequecy is 1.2 f' . If the velocity of sound is v, then the acutual frequency f_(0) is

If source and observer both are relatively at rest and if speed of sound is increased then frequency heard by observer will
